METHOD OF AND APPARATUS FOR' HEATING AND FLARING LAMP-CHIMNEYS.

SPECIFICATION forming part of Letters Patent No. 617,922, dated January'17, 1899..

I Application filed March 7, 1898- io all whom it may concern:

Beit knownthat 1, WILLIAM BUTTLER, of

diana,-have invented a new and useful Im-- provement in Methods of andApparatus for Heating and ,Flaring Lamp Chimneys, of

which the following is a full, clear, and exact description, referencebeing had to the accompanyingdrawing, forming part of thisspecification, in which the figure is a sectional side elevation ofapparatus constructed in accordance' with my invention.

My invention relates to the finishing of ing the ends of the chimneysand also flaring them preparatory to the crimping. operation when suchcrimping is carried out.

In the drawing, 2 represents a heatingfurnace, which may be of square orany desired shape, and into which projects a gasburner 3. The furnace isprovided with a hole 4'in its top for the entrance of the chimable snap5, having rings or collars '6, which rest upon brackets 7 and are heldin place by guide-lugs 8 upon the brackets. The upper end of this snapis provided with a pin' or button 9, arranged to enter a hollow shaft10, and with a projecting lug 11,. arranged to be engaged by a pin 12upon the shaft 10 whenever this shaft is depressed. The upper end of theshaft 10 is'secured to a sliding cross-head 13, guided between suitablestandards 14 and supported upon a rope or flexible connection 15,extending to a foot-1ever 16. A bevel-wheel l7 surrounds the shaft 10and is provided with a spline connection with this shaft, thisbevel-wheel intermeshing with'another, 18, mounted .upon a driven shaft19.

20 is a vertical standard, upon which and the standard 21, extendingfrom the furnace, In order to cool the snap-rod, so that it may behandled by the workmen, I provide a cooling means, such as the nozzle22, which is connected to driven upon the rod. Any other suitable meansfor keeping the rod cool may be employed without departing from myinvention.

In carrying out my improved method a chimney is clamped within a snap 5,and this scan Nb. 672,74. (No model-l snap being placed upon thebrackets 7, the

operator having lifted the cross-head 13 re-- moves his foot from thelever 16, and as the cross-head and shaft 10 descend the pin 12 tionbetween theshaftlO and the snap, and

lifts the snap from its'supports and immediately crimps the flared andheated chimney.

The advantagesof my invention result from the rotating of the chimney ina vertical position during its heating. The rotation prevents thernnning down of the glass, which would otherwise occur on account of theheat necessary to soften it for crimping, and the vertical positiongivesa uniform distribution of the heat and prevents distortion of theshape of the chimney. The chimney may, if desired, be heated in thismanner without flaring out, and I intend to cover its heating whilebeing rotated in vertical position whether it is flared or not. Acrimping-machine may be placed adjacent to the heater- The constructionand. arrangement of theapparatus employed may be varied widely withoutdeparting from my invention, since What I claim is-- v 1. Thecombination with a furnace having a hole or slot in its top, ofsupports, carrying holders above and in. line with the hole, a snapremovablefrom and arranged to be temporarily supported in the holders ina vertical position with its contained article having its lower endexposed to the heat within the slot, and detachable connections arrangedtorotate the snap when placed in the holder; substantially as described.

2. The combination with a furnace having a hole or slot in its top, ofsupports carrying. holders above and in line with the hole, a removablesnap arranged to be temporarily supported in the holders in a verticalposiend exposed to the heat within the slot, con-v,

- nections arranged to rotate the snap when placed in the holder, andmeans for cooling the snap-rod when in operative position; substantiallyas described.

3. The combination with a furnace having a hole or slot in its top, of aholder arranged to support a removablesnap in a vertical position overthe hole, mechanism for rotating the snap when in place, and a pipearranged to direct a cooling blast against the snap-rod; substantiallyas described.

4. The method of heating and flaring chimneys and similar articles,consisting in=supporting them ina depending position, rotating them, andheating the lower ends during rotation sufiiciently to cause Ila-ring bycentrifugal actionfsubstantiallyas described.

5. The method of heating and flaring ehi1n- 20 'neys, consisting insupporting them in a de- In testimony whereofI have hereunto set -myhand.
